Diaqua-bis(4-methyl-benzoato-κO)bis-(nicotinamide-κN)manganese(II).

In the mononuclear title complex, [Mn(C(8)H(7)O(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], the Mn(II) ion is located on a crystallographic inversion center. The asymmetric unit contains one 4-methyl-benzoate anion, one nicotinamide (NA) ligand and one coordinated water mol-ecule. The four O atoms in the equatorial plane around the Mn(II) ion form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two pyridine N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 9.01 (7)°, while the pyridine and benzene rings are oriented at a dihedral angle of 42.44 (5)°. In the crystal structure, inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, and O-H⋯π and C-H⋯π inter-actions link the mol-ecules into a two-dimensional network parallel to (001).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
